Title: Improvements in and relating to a process for the manufacture of high density polyethylene compositions
Inventor: SKOROSZEWSKI WLADYSLAW HENRY
IPC: C08J3/22
Filed: 1961-01-04
Abstract: A process for the manufacture of high density polyethylene (i.e. density at least 0,94) compositions by compounding said polyethylene with additives employing the masterbatch technique, comprises blending part or all of the polyethylene additives with a low density polyethylene (i.e. density below 0,94) so as to produce a masterbatch, and subsequently blending this masterbatch with the high density polyethylene.  Small amounts of other monomers, e.g. butene, may have been copolymerized with the ethylene.  The additives may be pigments, antioxidants, stabilizers, lubricants, and particularly carbon black.  An example describes the compounding of a high density polyethylene containing N,N1-di-beta-naphthyl-p-phenylene diamine with a masterbatch of low density polyethylene and carbon black.  The compositions may be formed into shaped articles, e.g. tubes. Specifications 471,590, 799,392, 799,823, 801,031, 803,198, 807,644, 830,824, 867,556 and 935,625 are referred to.

Abstract: 1417631 Injection moulding H STOBERL 3 Jan 1973 391/73 Heading B5A [Also in Divisions B7 and E1-E2] In a method of making a member 4, e.g. a door for a cupboard, room or vehicle, having a foamed core 7 and two outer walls 5, 6, the walls are disposed in the cavity of a mould (1, 2), Fig. 1 (not shown) with an edge of each wall in contact with an insert 3 extending into the cavity, and fluent settable foamed material injected into the cavity. The insert has an anchoring portion 3c to anchor it in the foamed core and a locating portion 3a received in a groove (2a) in one mould part. After removing the member from the mould a part 3g of the insert is severed at 3h and a snap-in member 3d inserted into a recess 3b exposed by the cut. The member 3d is retained in the recess 3b by rearwardly directed teeth 3e on a central web. The outer walls 5, 6 may be of synthetic resin with further layers, e.g. of reinforcing mats or fibrous fleeces. The insert 3 may be of rubber, PVC or metal and its surface may be roughened, corrugated or plastics coated. In Fig. 3a (not shown) the member 4 comprises a boat deck, engine or boot cover or roof for a vehicle and the insert has two locating portions 3a received in corresponding grooves in the two mould halves. In Figs. 4a ... 4c (not shown) the insert has anchoring lugs 3c in the form of a dovetail, which may have a corrugated surface. In Figs. 5a, 5b (not shown) additional walls (5a, 6a) are introduced into the mould and additional inserts (3n) can be adjusted to different depths of insertion. The articles may be a vehicle door, wall or container &c. In Fig. 6a the insert 3g has covering flaps 3f parallel with the walls 5, 6 so that a substantially rectangular sealed edge is produced. The cut is made at a narrowed portion 3w, no recess being provided. The insert can be made in two parts (see also Fig. 6g, not shown) which are stuck together, and each may be provided with a recess (see Figs. 7a-7f, not shown). In Figs. 8a ... 8h (not shown) the inserts are designed as connecting members for connecting two or more members arranged in line or at right angles.

Abstract: 658,638. Cyaniding gold ores, WILKINSON HIGH FREQUENCY, Ltd. Jan. 7, 1949, No. 491. [Class 82(i)] A process for extracting gold from gold ore pulp or tailings comprises mixing the latter with a solution of cyanide, passing ozone through the mixture and subjecting it to the action of a high frequency electromagnetic field. The mixture may also contain hydrated lime. The process may be carried out in the apparatus shown in the drawing in which a vessel 1 contains the reaction mixture and is heated to 110‹F. on a water bath 2. Ozone is produced by passing air through electrolyzer tube 8 and is introduced into the mixture through tube 3. The high-frequency electromagnetic field is applied between electrodes 4 and 5. Evaporated cyanogen gas passes through tube 6 to vessel 7 in which it is absorbed in a solution of sodium chloride which may then be used for treatment of a further batch of pulp or tailings.

Abstract: 420,470. Plucking poultry. BINGHAM, G. C., The Friary, Maldon, Essex. Jan. 6, 1934, No. 581. [Class 28 (ii)] In a machine for plucking and stubbing poultry of the kind wherein the plucking is effected by a number of co-axial, rotary, tilting disc-like members, the feather-removing fan is arranged co-axially with the discs. The discs are arranged to tilt about two different axes, and the housing for the discs comprises hinged spring-pressed side walls which carry the rollers for effecting the tilting of the discs. As shown in sectional plan in Fig. 3, the fan 14 is carried on a sleeve 15 driven by a pulley 17, and the discs 25, 24, 28 are carried on a square sectioned end 21 of a shaft 18 passing through the sleeve 15 and driven by a pulley 20. One end disc 23 is a plain disc, whilst the other end disc 24, Fig. 6, is provided on one face with plates 25 carrying projections 26, 27 forming two tilting axes, one on each side of the centre of the disc. The intermediate discs 28, Fig. 4, comprise rings 29 with cross plates 30 and tilt projections 26, 27, the spaces 31 being left for the easy removal of the plucked feathers by the fan suction. All the discs have square central holes 22 of a size sufficient to permit the tilting on the square shaft end 21. The projections 26, 27 are arranged at different angular positions on different discs. The sides 32 of the housing for the discs are pivoted at 33 and resilient means, connecting the sides 32, permit them to approach, or recede from, one another. The pressing rollers 38 are carried by the sides 32. The space between the edges of the sides 32 is closed by a removable U-shaped band 34 connected by spring means to the conduit 12 connecting the plucking means and the fan casing. The opening 35 at which the bird is presented to the plucking-discs is formed in the band 34. The outlet of the fan has means for the attachment of a sack, the mouth of which is kept open by a wire hoop. Specifications 309,004, [Class 28 (ii)], and 368,791 are referred to.

Class 39(1) Reheating of a phosphor at 200-400‹C. for 10-60 minutes improves its electroluminescent properties. A mixture of zinc sulphide, zinc oxide (e.g. 25 per cent), and (.01-0.1 per cent) of a copper salt, e.g. (.05 per cent of copper nitrate), is fired in a closed crucible in air at 900-1040‹C. and thereafter reheated at 200-400‹C., e.g. 300‹C. in either a reducing, neutral or oxidizing atmosphere, hydrogen or carbon monoxide being the most effective medium. The first firing step may be followed by quick cooling. The phosphor is washed with dilute acid e.g. acetic acid, and with sodium or potassium cyanide solutions to remove excess zinc oxide and copper sulphide. The effects of reheating and washing on colour shift and chemical composition are discussed. Silver, lead and lanthanum may be secondary activators.

Title: Improvements in or relating to the circulation of gases in processes for the production of valuable hydrocarbons by heat treatment of compounds of carbon with hydrogenating gases under pressure
IPC: C10G1/06
Filed: 1936-01-10
Abstract: <PICT:0468709/III/1> In processes for the production of valuable hydrocarbons by the heat treatment of carbonaceous materials with hydrogenating gases under pressure, e.g. destructive hydrogenation, hydrogenation of unsaturated compounds, and the treatment of carbon monoxide with hydrogenating gases, of the kind in which the gases and vapours leaving the reaction vessel are returned wholly or in part thereto, the gases &c. are recycled with the aid of an injector operated by a liquid which may be used to wash the gas.  Part of the liquid may be withdrawn from the cycle and used as a cooling medium for the reaction.  A mixture of hydrogen and crude materials is passed through a heat exchange l and a preheater k to reaction chambers i, i<1>.  The reaction products pass off through a line o through the heat-exchanger l to a separator m. The gaseous products separated are passed through a line p into the bottom of an injector a through which they are injected with the aid of liquid from a pump c into a washing vessel b maintained under pressure.  The gases pass off through a line q to mix with the initial materials flowing through the pipe n while the washing liquid is recirculated to the pump c.  Part of the liquid may be divided off through a line e, and injected as cooling medium through pipes f into the reactors.  The washing liquid is regenerated by circulating it through lines d, s, and a pressure release vessel g.  A liquid which takes no part in the reaction, e.g. anthracene oil or other oil of high boiling point is preferably used as the washing medium.
